HEAT-CONTROLLING- DEVICE' FOR RADIATORS.

Specication of Letters Patent.

Patented May '7, 1912.

Application filed July 7, 1910. Serial No. 570,878.

To all whom t may concern:

Be it known that I, THOMAS K. LYsINGEn, of VVilkinsburg, Alleghenycounty, Pennsylvania, have invented a. new and useful Heat-ControllingDevice for Radiators, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, formingpart of this specification, in which- Figure 1 .is a view, largelydiagrammatic, illustrat-ing the application and use of my invention;Fig. 2 is a face view of the valve device; Fig. 3 is a section on theirregular line lll-TH of Fig. 2 looking in the direction of the arrow;and Figs. 4 and 5 are detail sectional views taken on the line TVMV ofFig. 2 showing the valve in different positions.

My invention has relation to heat-controlling means for radiators, andrelates more particularly to that class of devices in which theradiators are provided with fluid pressure valves, such as air valves,and which are controlled from a more or less distant point such as aconvenient place on the wall of thc room or apartment in which theradiators are located. Various automatic devices for this purpose havebeen proposed, operating by thermostatic action, and some of these havegone into extended use. A great deal of difficulty has been experienced,however, by reason of the fact that these devices constantly get out oforder and fail to work properly, and there are more or less constantcomplaints from the tenants of large buildings in which such devices areinstalled. Practical experience with such devices has shown that theordinary tenant is not particularly desirous of a controlling devicewhich shall regulate the temperature automatically to any desireddegree, but is desirous of a simple and convenient device, capable ofmanual manipulation by which he can easily and readily turn the heat onand 0H from the radiators from a convenient point on the wall.

My invention is designed to provide such a device.

lt also furnishes a simple ,and inexpensive device which is adapted totake the place of the thermostatic devices now used, being capable ofattachment to the same wall plug as those devices and without disturbingthe pipe connections which furnish the pressure for opening the radiatorvalves.

Referring to the accompanying drawings,

t-he numeral 2 designates a steam radiator having a steam admission pipe3 provided with a control valve 4. This valve is of the well known typewhich is held open by the action of a spring and is closed by means ofair pressure admitted from a suitable source. 5 designates an air supplypipe leading to this valve through a wall plug 6 also having a pipeconnect-ion 7 with a suitable source of compressed air such as indicatedat 8. The wall plug 6 which I have herein shown is the ordinary plugwhich is now in use with the well known form of thermostatic regulator,and the pipes 5 and 7 are the usual pipes which are connected to thisplug.

The connection between the pipes 5 and 7 is effected by the usual portor passa-ge 9 in the wall plug, which is provided with the usualcut-oft' valve 10, which enables the valve 4 to be opened in case theusual thermostatic valve does not operate. This valve 10 may or may notbe employed in connection with my invention, and prefer ably would notbe where my invention is installed independently of existing systems.l/Vhere, however, it is used to replace existn ing systems, this valvemay be retained to avoid expense in changing the wall plug.

In accordance with my invention, l place a suitable washer 11 on theouter face of the wall plug 6, this washer having therethrough ports 12and 13 for communication with the pipes 5 and 7. I also secure to thewall plug, as by the screws 14, a valveseating plug 15 having therein avalve 16 with a spindle 17 projecting through a suitable packing 17a andretarding nut 18. The outer end portion of the valve stem or spindle 17is provided with a combined pointer and handle 19 arranged to movebetween the stops 20. When this handle and pointer is in contact withone of the stops the valve plug 16 is in position as shown in Fig. 4 toconnect the pipes 5 and 7 and admit air to the valve 4; whereas, whenthe pointer is in the through position, the port leading to the pipe 7is cut oif and the pipe 5 is connected with a suitable exhaust. 16a is awasher against which the inner end of the valve 16 seats. For thispurpose the valve plug 15 is provided with a port 21 which communicateswith the pipe 5 through the opening 12 in the washer, and also with aport 22 which communicates with the pipe 7 through the opening 13 in thewasher. The valve plug is provided with a port- 23, which, in theposition shown in Fig. 4:, connects the two ports 21 and 22. This valveis also provided with an exhaust port or passage 24E,y which in itsother position connects with the port 22 to provide an exhaust outwardlythrough the stem of the valve.

My invention forms an exceedingly cheap,

disturbing existing connections or requiring any cutting into ordefacement of the walls of the building. The valve mechanism is shown asinclosed in a suitable casing 25, which may be of any desired neat orornamental appearance.

lll hat I claim is l. The combination with a radiator having aconnection for supplying` it with a heated heating fluid, a valve forcontrolling the supply of such iiuid, and a motor for actuating thevalve, of a wall plug located in the wall of the apartment in which theradiator is placed, a pipe connection leading from said plug to theradiator valve motor and also from said plug to a source of pressuresupply, an attachment secured to the plug and having ports therein whichcommunicate with the said pipe connections, and a hand valve mounted insaid attachment and controlling said ports, substantially as described.

2. The combination with a radiator having a fluid pressure valve, amotor therefor, of a wall plug located at a distance from said valve, apipe connection leading from the wall plug to the radiator valve motor,a

ter with the passage in the casing leadinY f D from the tirst pipeconnection when the valve is moved in another position, and a valve stemconnected to said valve extending through the casing; substantially as(lescribed.

3. rEhe combination with a radiator having a Huid pressure valve, amot-or therefor, of a wall plug located at a distance from said valve, apipe connection leading from the wall plug to the radiator valve motor,a second pipe connection leading from the plug to a source of pressuresupply, a casing connected to said wall plug having a plurality of portscommunicating with said pipes, a rotary valve mounted in said casing,said valve having a passage arranged to register with said ports toconnect the two pipes when the valve is in one position, there being asecond passage open to the atmosphere in said valve arranged to registerwith the passage in the casing leading from the iirst pipe connectionwhen the valve is moved in another position, a valve stem connected tosaid valve extending through the casing, and a combined pointer andhandle connected to said valve stem; substantially as described.

In testimony whereof, I have hereunto set my hand.
